Platinum(II), palladium(II), nickel(II), and gold(I) complexes of the “electrospray-friendly” thiolate ligands 4-SC₅H₄N- and 4-SC₆H₄OMe-

The series of platinum(II), palladium(II), and nickel(II) complexes [ML₂(dppe)] [M = Ni, Pd, Pt; L = 4-SC₅H₄N or 4-SC₆H₄OMe; dppe = Ph₂PCH₂CH₂PPh₂] containing pyridine-4-thiolate or 4-methoxybenzenethiolate ligands, together with the corresponding gold(I) complexes [AuL(PPh3)], were prepared and their electrospray ionization mass spectrometric behavior compared with that of the thiophenolate complexes [M(SPh)₂(dppe)] (M = Ni, Pd, Pt) and [Au(SPh)(PPh₃)]. While the pyridine-4-thiolate complexes yielded protonated ions of the type [M + H]+ and [M + 2H]²+ ions in the Ni, Pd, and Pt complexes, an [M + H]+ ion was only observed for the platinum derivative of 4-methoxybenzenethiolate. Other ions, which dominated the spectra of the thiophenolate complexes, were formed by thiolate loss and aggregate formation. The X-ray crystal structure of [Pt(SC₆H₄OMe-4)₂(dppe)] is also reported

Everything but the kitchen sink: An analysis of bacterial and chemical contaminants found in syringe residue from people who inject drugs

BACKGROUND: People who inject drugs (PWID) are at high risk of severe wounds, invasive infections, and overdoses. To date, there are few data on the bacterial and chemical contaminants PWID are exposed to when using illicitly manufactured fentanyls and stimulants. METHODS: Previously used injection drug use equipment was recovered in St Louis, Missouri, by harm reduction organizations over a 12-month period. Syringe residue was analyzed for bacterial contaminants by routine culturing followed by whole genome sequencing of single bacterial isolates. Chemical adulterants in syringe residue were identified by liquid chromatography-mass spectrometry. RESULTS: Bacteria were cultured from 58.75% of 160 syringes analyzed. Polymicrobial growth was common and was observed in 23.75% of samples. CONCLUSIONS: Analysis of syringe residue from discarded drug use equipment demonstrates both chemical and biological contaminants, including medically important pathogens and adulterants

Identifying the gaps regarding exposure to aeroallergens in schools: systematic review

This research was funded by the Instituto Politécnico de Lisboa, Lisboa, Portugal for funding Project IPL/2023/FoodAIIEU_ESTeSL. H&TRC authors gratefully acknowledge the FCT/MCTES national support through the 2023.01366.BD and IPL/2022/InChildhealth/BI/12M.Background: Allergic diseases are a major concern in high-income countries, and their occurrence continues to increase worldwide. Despite previous studies reporting the health effects of exposure to both chemical and (micro)biological agents, aeroallergens have been less well studied. Most studies have focused on exposure to indoor allergens at home. However, exposure can happen in other environments, including in schools where children spend much of their time. Review questions: What are the most common indoor allergens in schools? What methods (sampling and assays) are applied to measure the levels of indoor allergens in schools? What are the levels of indoor allergens in schools? What are the determinants of indoor allergens in schools? Which areas of schools have the highest levels of allergens (e.g., wet areas/bathrooms)? What are the effects of exposure to indoor allergens on asthma, asthma-like symptoms, asthma control, allergic sensitization, and allergic diseases?info:eu-repo/semantics/publishedVersio
